Overview of this book

The foundation for many modern programming languages such as C++, C#, JavaScript, and Go, C is widely used as a system programming language as well as for embedded systems and high-performance computing. With this book, you'll be able to get up to speed with C in no time. The book takes you through basic programming concepts and shows you how to implement them in the C programming language. Throughout the book, you’ll create and run programs that demonstrate essential C concepts, such as program structure with functions, control structures such as loops and conditional statements, and complex data structures. As you make progress, you’ll get to grips with in-code documentation, testing, and validation methods. This new edition expands upon the use of enumerations, arrays, and additional C features, and provides two working programs based on the code used in the book. What's more, this book uses the method of intentional failure, where you'll develop a working program and then purposely break it to see what happens, thereby learning how to recognize possible mistakes when they happen. By the end of this C programming book, you’ll have developed basic programming skills in C that can be easily applied to other programming languages and have gained a solid foundation for you to build on as a programmer.

Chapter 5: Exploring Operators and Expressions

So far, we have seen how values are stored to and from variables. Simply storing and retrieving values to and from variables, while important, is only a small part of handling values. What is far more important is the ability to manipulate values in useful ways, which corresponds to the ways we manipulate real-world values, such as adding up our restaurant bill or calculating how much further we have to go to get to grandma's house and how much longer that might take.

The kinds of manipulations that are reasonable to perform on one or more values depend entirely on what kinds of values they are, that is, their data types. What makes sense for one data type may not make sense for another. In this chapter, we will explore the myriad ways that values can be manipulated.

The following topics will be covered in this chapter:

  • Understanding expressions and operations
  • Exploring operations on numbers and understanding the...
